           Summary: Konsole crashes when changing tabs
           Product: konsole
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: konsole-devel kde org
        ReportedBy: macberry mail ru

Version:           1.3.90 (using KDE 3.2.90 (CVS >= 20040117), Gentoo)
Compiler:          gcc version 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r1, propolice)
OS:                Linux (i686) release 2.6.6

Quite often, when changing tabs, i get a crash from my so-belowed terminal program... Seems like a null pointer in activateSession...

Using a recent CVS (gentoo compiled)

Here is the crash report (pretty identical every time it happens).

Using host libthread_db library "/lib/libthread_db.so.1".
[Thread debugging using libthread_db enabled]
